The Santa Rosa Press Democrat just posted my Tuesday column about Alex Smith and the 49ers’ quarterback vacancy. I post this with some trepidation as things are changing rapidly and I don’t want this thing to be out of date. But that’s daily journalism. I argue that Jim Harbaugh blew it with Peyton Manning and, if he’s not careful, he’ll also blow it with Smith, whom the 49ers now need. You may agree or disagree. To read my column, please click here.
